Y,BO'ITOM DELIVERY BODY FOR VEHICLES.

Application-*filed August 20, 1927. Serial No.` 214,318. Y

rIhis invention relates to vehicle bodies and more particularly to means whereby a load of material such as sand, gravel, coal, grain, trash,`and the like can be quickly delivered downwardly through the bottom of 'the body., said body being lso constructedtion, a vportion thereof Will be' elevated while the reinaining'portion will be lowered thus insuring rapid dumping-of the contents of the body.

' i A further object is to provide a structure of'this character which is' durable and efficientv and the partsof which can be operated easily. y'

"With the foregoing andother objects in view which will appear as the description proceeds, the invention resides in the `combination and. arrangement of parts and in .the details of construction hereinafterV dechanges inthe vprecise embodiment of the invention herein disclosed vvmay be `made within the scope of what is claimed, without departing from the'spirit of the invention.

In the accompanying drawings. the preferred form ofthe invention has been shown.

Figure 1 isa vertical transverse section lthrough the vehicle body, the yParts beingr shown in their normal or load retaining positions. y Y

Figure. 2 is a plan view showing the bottom of the body inv dumping position, the upstan ling frame above the body being shown in section.

Figure Sis arbottoin plan vievv` of the dump body77V showing the parts closed vfor retaining aV load. i y f Fig re is a vertical longitudinal section, the bo.f1oin of the body being indumping or load releasing'position.

Referring to the figures by characters of reference yl designates the usual bolsters supported by wheels 2 and on these-holsters are mounted the side sills 3 and 4 of the vehicle body. These sills are suitably connected at their ends by framemembers 5 and 6. A

central beam 7 connects'the frame members 5 and adjacent their centers and is-a'lso connected at intervals with the sill 4 by crossl strips 8.' Up'standing from the sills Sand 4 are thexside panels 9,v and 10 of the vehicle body, these being connected at the yfront and backbyk front and rear'panels 11 and 12 respectively. Upwardly and laterallyy in-y clined side boards13 y,can be connected :to the side panels 9l and 10, each of these side boards having an extension board- 14 hing` PATENToFFicaj or) l edly attached vto its upper edge'asshown at 'l 15.v The extensions 14 can? be held in upstanding positions by rods 16 or the like havingv hooks 17 for engaging eyes 18 upstanding from the lower portions of the side boards 13. Posts 19V extend upwardly from the front and back portions of the vehiclebody and are connected by a top'beain 20. These posts can bereinforced by brace Wires 21 or 'the like connected,y to the eyes 18 as shown particularly inFigure 1. The 19 constitute"supports for a shaft 22 having any'suitable means at one end thereof, such as a. handle 123,. whereby it can be rotated.

To Ythis shaft are secured lifting cables 24r posts 4 which extend downwardly and are suit-ablysecured to 'a movable side panel 25'normally supported 1n an-upstanding position against the linner side of the panel 10 asshown inV Figure 1. The loweredge of this panel 25 is hingedly connected asat 26' to a slat 27.

A series of additional slats28 are 'provided' and are all hingedly-connected to each other and to the slat 27 so as to lprovide approxi'- mately one-half of the,y bottom of thevehicle body. These slats are hingedly connected to` an intermediate stationary slat 29 extending longitudinally of the body and hingedlyonnected to the slat 29 are slatsBO. -Any desired number of these slats 30 inay be employed, they being hingedly connected as d shown at 31 and constitutingthe remainder of the bottoni portion of the'vehi'cle body. It might berstated that the cables .24 are not attached directly to the panel 25 but are and throughavhich*the brace rods or cables i attached toeyes-32 extending from the panel y i 21 extend.' These rods or cables thus serve not only tobrace the posts 19 but also constitute guides for the eyes l32 during the' dumping operationas hereinafter explained.

Suitablyl guided Withinl the sills 4and the intermediate beam 7 Vare transversely extended slides l33 each of which has la' roller 34 at one endvA. rack bar 35 Ais formedinl ,A

V,the rollers 3e Carried -t-hereby supporttlie .l springs adjacent slat 30 so that the bottom is thus maintained closed. It will be apparent, however, that when the racks are shifted longitudinally to the dotted line position vshown in Figure l by rotating the gears 36,

ther rollers 3,4 will be pulled laterally from under the slats y30 and Vthese slats will thus be :tree to drop downwardly under the weight of the load supported thereby. For the purpose oi' preventing the lowered slats from dropping against the bolsters under the body, one or more springs 4L()V are connected to the slat 30 nearest panel 9, these being constantly under tension as shown. i f

lVhen the rollers 34 are withdrawn from under the slats 8O springs 40 will pull the slats 30 downwardly and laterally so that they will fold under vthe intermediate or stationary beam 7 as shown by broken lines in Figure 1. Normally, however, the slats 30 are supported in closed position and the same is likewise true of ythe slats 27 and 28.

"seat il can be provided for the driver,

this seat being liingedly connectedk at 42 to the front panel 11. Vhen this seat is not in use it can be in an upstanding position as shown by broken lines in Figure l at which time it will rest within a recess 43 formed in lthe back tace oi the front post 19. Y This seat can be 4supported in any suitable manner when lowered. i

Assuming that a load is contained within n the body and the parts are all positioned asl shown in Figure 1,it is necessary,when the load is to be dumped to first rotate the gears l36 so asto shift the slides 33 laterally and withdraw the rollers 34C from under the slats 30. These 4slats will promptly swing downwardly to the dotted line position shown in Figure l, thereby releasing that portion of the load above and adjacent the slats 30.

i Following this operation the shaft 22 is v guides or braces 2l.

rotated to wind the cables 24 thereon. As a result of this action the panel 25 will be pulled upwardly, vit being guided in this in ovement by the eyes 32 travelling along the .by the release ot the slats 30. Y Consequently all portions of the contents will be quickly As the panel thus delivered. Following this operationthe parts are returned to their normal positions, the return ol the slides 33 causing the slats to shift back to separate positions while the lowering of the panel 25 will cause the slats 27 and 28 likewise to assume closed positions.

lt is toy be understood of course thatl various modifications oi' this struct-ure can be used without departing vfrom the spirit of the invention. i

What is claimed is: l. A vehicle body, separate groups of hingedly connected members constituting f the bottom ofthe body, mea-ns for supporting the members of one group in load retafning positions, means for shifting said supporting means to release the members of A,

.said group for downward movement under the weight oi the load supported thereby, and means for elevating the members of the other group to deliver the load supported thereby through the space provided by the 'lowered members of the lirst group.

`2. A vehicle body, separate groups ofv hingedly connected members constituting the bottom of the body, means for supporting` the members of one group in load re-l taining position, means for shifting said supporting means to release the members oi said group for downward 4movement under the weight of the load supported therev f by, and means for elevating the members or' the other group to Vdeliver to load supported thereby through the spa-ceprovided by the lowered members ofthe first group, said last mentioned means including guides, means on one of the members of said group for slidably engaging the guides and mechanisin for drawing said means along the guides to elevate the members of the group. 3. The combination 'with a dump body and separate groups of movably connected lll) ing the members of one group in load retaining position, ineans'for simultaneously actuating the slides to release said members, means for automatically folding the released members downwardly and laterally, and means for elevating the members of the other group to deflect the loadI supported thereby into the opening provided by the lowered members of the first group.

5. A vehicle body including `hingedly connected members constituting the bottom thereof slidable means for supporting some of the members in load retaining position, means for simultaneously actuating said slidable means to release the supported mem! vbody and against one ofthe side panels,

hingedly' Connected members constituting the bottom of the body, said members being` arrangedin separate groups, one of said groups being hingedly connected to the movable panel, slida-ble supports for the members of the other group, means for simultaneously actuating said .supports tofrelease the members supported thereby, and meansv connected to the movablev panel for succes sively raising said panel and the members of the other group to lift the loadsupported thereby and direct it to the opening provided bythe released members of the irst group. y,

7. The combination With a vehicle body including side and end panels, of a movable y side panel normally arranged Within the body and against one of the side panels,

hingedly l connected members constituting the bottom of the body, saidfmembers Vbeing arranged in separate groups, one of said groups bemg hmgedly connected to the movable panel, slidable supports for the mem#v bers of the other group, means for simul taneouslyactuating said supports 'to release A the Ymembers supported thereby, means connected to the movable panel for successively raising-'said paneland'the members ofthe first group to lift rthe load supported thereby` and direct it to the opening provided by the released members ofthe second group,

and resilient means for folding the membersY of the second group laterally from under the opening provided thereby when released.

In testimony that -I claim the foregoing as my own, I have hereto affixed my signature.
